To access data services, you reference the unique service URL for the data from your application.
Steps
You can access hosted layer (items) with tools in your portal or ArcGIS Pro. If you are building applications, you can also use client APIs or the REST API.

List items
To access hosted layer (items) that you own, you need to sign in to your portal. This gives you access to items in your account.
Find items by ID
If you know the ID for a hosted layer (item), you can access the item page directly with a URL.
https://www.arcgis.com/home/item.html?id=<ITEM_ID>Example: https
If the item is is private, you will be prompted to sign in and redirected to the item ID URL:
https://<ORG_ID>.maps.arcgis.com/home/item.html?id=<ITEM_ID>Search for items by ID
If you would like to search for all hosted layer (items) that are public, you can do so using ArcGIS Online.
Example: https
To get data, you need the service URL for your hosted layer (item) and you can access the layer directly or with a query to the service. The easiest way to find the URL is to go to the item page.
To access feature layer data, you execute a query to request a subset of the features from the feature layer. To learn more, go to Hosted feature layers.
